Abstract We have developed a new method for preimplantation diagnosis of inherited diseases. Our procedure for the identification of point mutations in single cells combines whole-genome amplification using 15-mer random primers (primer extension preamplification, PEP) with a single locus-specific PCR amplification, followed by detection of the mutation by solid-phase minisequencing. The procedure was evaluated by detecting three disease-causing mutations and seven polymorphic nucleotides located on different human chromosomes from single granuloma and blastomere cells. The correct genotype of the cell was identified at 96% of the nucleotide positions analyzed, showing that a representative part of the genome is amplified during PEP. We estimate that PEP yielded at least 1000 copies of the genome. The quantitative nature of the solid-phase minisequencing method allowed us to notice that preferential amplification of one allele occurs at heterozygous loci during PEP, which is a potential problem in preimplantation diagnosis.
